The effect of combining nifedipine with short- and long-acting nitrates or with propranolol was also evaluated.<\/jats:p>\n                  <jats:p>In consideration of the statisically significant reduction in the number of anginal attacks per day, p&lt;0.001, together with the non-significant mean changes in blood pressure and pulse rate as well as the compatability with the other drugs, it is concluded that nifedipine is a very useful drug, in a dose range of 30\u2013120 mg per day, for the treatment of Prinzmetal's Angina. Recorded side-effects were of minimal severity and in no case caused nifedipine therapy to be discontinued.<\/jats:p>","DOI":"10.1177\/030006057900700505","type":"journal-article","created":{"date-parts":[[2017,1,11]],"date-time":"2017-01-11T13:23:55Z","timestamp":1484141035000},"page":"360-369","source":"Crossref","is-referenced-by-count":5,"title":["A Retrospective Evaluation of Nifedipine Therapy in Prinzmetal's Angina"],"prefix":"10.1177","volume":"7","author":[{"given":"Roy","family":"Battye","sequence":"first","affiliation":[{"name":"Delbay Research Corporation, Division of Medical Research, Florham Park, New Jersey, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carol M","family":"Ordille","sequence":"additional","affiliation":[{"name":"Delbay Research Corporation, Division of Medical Research, Florham Park, New Jersey, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1979,9,1]]},"reference":[{"key":"bibr1-030006057900700505","first-page":"229","volume-title":"3rd International A dalat Symposium","author":"Bidogggia H","year":"1976"},{"key":"bibr2-030006057900700505","first-page":"283","volume-title":"3rd International Adalat Symposium","author":"Ebner F","year":"1976"},{"key":"bibr3-030006057900700505","first-page":"220","volume-title":"3rd International Adalat Symposium","author":"Ekelung L G","year":"1976"},{"key":"bibr4-030006057900700505","doi-asserted-by":"publisher","DOI":"10.1378\/chest.60.6.522"},{"key":"bibr5-030006057900700505","first-page":"334","volume":"22","author":"Grun G","year":"1972","journal-title":"Arzneimittel Forschung"},{"key":"bibr6-030006057900700505","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.1.6121.1181"},{"key":"bibr7-030006057900700505","first-page":"105","volume-title":"3rd International Adalat Symposium","author":"Lydtin H","year":"1976"},{"key":"bibr8-030006057900700505","unstructured":"Maxwell A E (1961) Analysing Qualitative Data.
